SPECTROPHОTОMETRIC METHOD FOR DETERMINATION OF TOTAL POLYHENOLIC CONTENT IN SWEET CORN

Abstract

Polyphenolic compounds also known as polyhydroxyphenols, are a group of secondary plant metabolites that can be found as simple molecules but also as highly polymerized compounds such as tannins. Many food types are considered as a great source of polyphenolic compounds, such as fruit, herbs, vegetables, grains and so on. Therefore, the goal of the present study was the determination of total polyphenolic content (TPC) in two sweet corn cultivars Messenger F1 and Sentinel F1 using UV – Vis spectroscopy. TPC in sweet corn are evaluated by Folin – Ciocâlteu method in relation with gallic acid as a reference standard. The obtained results reveled that the TPC in the hybrid Messenger F1 is
